Appendix B (TABLE B1). Relationships of the frequency of occurrence of species with the parametric variables vegetation type and northing, and tests of significance for these variables obtained from the full species models (GAMMs). Chenopod Mallee is used as the reference variable in the model, such that coefficients for vegetation refer to species responses to the Triodia Mallee vegetation in comparison with the reference variable. Significant responses (P < 0.05) are shown in bold type.
